Referring to FIGS. 1-3, a vehicle 10 includes a front seating assembly 14 and a rear seating assembly 18. The front seating assembly 14 may include an occupant sensor 22 that is configured to sense an occupant status of the front seating assembly 14. A proximity sensor 26 is utilized to sense the presence of an object 30 in an area behind the front seating assembly 14, such as a footwell 34. A rear door sensor 38 is configured to sense an opening of a rear door 42. A controller 46 may be employed to activate an actuator 50 to move the front seating assembly 14 forward based on the sensed occupancy of the front seating assembly 14, the sensed object 30, and a sensed opening of a door.

The vehicle 10 may include one or more of the front seating assemblies 14. In the embodiment shown, there are two front seating assemblies 14, namely, a driver seating assembly and a passenger seating assembly. A center console 54 may separate the two front seating assemblies 14. The center console 54 can include various storage compartments such as, cup holders 58 and a small item storage bin 62. The occupant sensor 22 can be positioned in one or more of the front seating assemblies 14. For example, the occupant sensor 22 may be positioned in a seat 66 of the front seating assembly 14. Alternatively, the occupant sensor 22 may be positioned in a seatback 70 of the front seating assembly 14. The occupant sensor 22 may be, for example, a weight sensor, a capacitive sensor, a radar sensor, a seatbelt-buckle engagement sensor, or the like for sensing whether or not the front seating assembly 14 is occupied.

The rear door sensor 38 can be positioned in the rear door 42 to sense an open position of the door. Alternatively, the rear door sensor 38 may be positioned proximal a B-pillar 74 for example, within or adjacent to a hinge assembly for the rear door 42. In another alternative, the rear door sensor 38 may be positioned in a C-pillar 78 in the vehicle 10 (e.g. within or adjacent to a latch for the rear door 42).

The proximity sensor 26 is positioned in the interior of the vehicle 10 in such a manner as to sense the presence of the object 30 in an area that is rearward of the front seating assembly 14. For example, the proximity sensor 26 may monitor the footwell 34 that is rearward of the front seating assembly 14 and sense the presence of the object 30. It is contemplated that suitable locations for the proximity sensor 26 include, but are not limited to, in the seat 66 of the front seating assembly 14, in a rearward portion of the seat 66, in the seatback 70 of the front seating assembly 14, in a rearward portion of the seatback 70, in the center console 54, in a rearward portion of the center console 54, in a floor board of the vehicle 10, in a seat base 82 of the rear seating assembly 18, in a backrest 86 of the rear seating assembly 18, or any other suitable location within the vehicle 10 that permits monitoring of an area rearward of the front seating assembly 14. The object 30 that is detected by the proximity sensor 26 can be for example, a child's car seat, a rear seat occupant, a cargo item, or the like.

Referring now to FIG. 4, depicted is a block diagram of the vehicle 10 in which a method of control ling a vehicle seating assembly, such as the front seating assembly 14, is implemented. The vehicle 10 includes the controller 46 in communication with one or more vehicle control modules 90. The vehicle control module 90 may be configured to relay information to the controller 46 from a variety of sensors. Exemplary sensors include the occupant sensor 22, the proximity sensor 26, the rear door sensor 38, a seatback pitch angle sensor 94, a fore-aft position sensor 98, and the like. The controller 46 may include a memory 102 having a seat position routine 106 contained therein that is executed by a processor 110 of the controller 46. The controller 46 may provide electrical power to the front seating assembly 14 via a power source 114 located on board the vehicle 10. More specifically, the controller 46 may be configured to control a fore-aft actuator 118 and/or a seatback pitch angle actuator 122 based on feedback received from the vehicle control modules 90. The fore-aft actuator 118 and/or the seatback pitch angle actuator 122 may serve as the actuator 50 shown in FIG. 1 that moves the front seating assembly 14 forward. The seat position routine 106 may include a variety of routines configured to cause the controller 46 to adjust the positioning of the front seating assembly 14. For example, the controller 46 may control the fore-aft position on a rail system 124 (FIG. 1) of the front seating assembly 14 via the fore-aft actuator 118 with feedback from the fore-aft position sensor 98. Additionally, the controller 46 may control the seatback pitch angle via the seatback pitch angle actuator 122 with feedback provided by the seatback pitch angle sensor 94. Communication between the controller 46, the vehicle control modules 90, the front seating assembly 14, the fore-aft actuator 118, and the seatback pitch angle actuator 122 can be facilitated by electrical connections 126. It is contemplated that alternative forms of communication between the controller 46, the vehicle control modules 90, the front seating assembly 14, the fore-aft actuator 118, and the seatback pitch angle actuator 122 may be used such as, wireless forms of communication (e.g. Bluetooth).

Referring again to FIG. 4, the seat position routine 106 of the controller 46 may be configured to pivot the seatback 70 of the front seating assembly 14 in a forward direction when it is determined by the controller 46 that the object 30 is present in the footwell 34 behind the front seating assembly 14. In a first example, the seat position routine 106 of the controller 46 may pivot the seatback 70 of the front seating assembly 14 in a forward direction when feedback from the vehicle control modules 90 indicate that the front seating assembly 14 is unoccupied and a cargo item has been placed in the footwell 34 that is rearward of the front seating assembly 14. In another example, the seat position routine 106 may pivot the seatback 70 of the front seating assembly 14 in a forward direction when feedback from the vehicle control modules 90 indicates that the front seating assembly 14 is unoccupied and a child's car seat has been placed in an area rearward of the front seating assembly 14, such as the rear seating assembly 18, as illustrated in FIG. 2. In yet another example, the seat position routine 106 may pivot the seatback 70 of the front seating assembly 14 in a forward direction when feedback from the vehicle control modules 90 indicates that the front seating assembly 14 is unoccupied and a rear seat occupant has entered the rear seating assembly 18 (e.g. feet and/or legs sensed in the footwell 34, occupant sensor in the rear seating assembly 18 indicates an occupied status, etc.) as illustrated in FIG. 3.

Referring further to FIG. 4, in a second example, the seat position routine 106 of the controller 46 may be configured to slide the front seating assembly 14 in a forward direction when it is determined by the controller 46 that the object 30 is present in the footwell 34 behind the front seating assembly 14. For example, the seat position routine 106 may slide the front seating assembly 14 in a forward direction when feedback from the vehicle control modules 90 indicates that the front seating assembly 14 is unoccupied and a cargo item has been placed in the footwell 34 that is rearward of the front seating assembly 14. The controller 46 may additionally verify that the front seating assembly 14 is in a position rearward of the forward-most position prior to activating the fore-aft actuator 118. In another example, the seat position routine 106 may slide the front seating assembly 14 in a forward direction when feedback from the vehicle control modules 90 indicate that the front seating assembly 14 is unoccupied and a child's car seat has been placed in an area that is rearward of the front seating assembly 14, such as the rear seating assembly 18. The controller 46 may additionally verify that the front seating assembly 14 is in a position rearward of the forward-most position prior to activating the fore-aft actuator 118. In yet another example, the seat position routine 106 may slide the front seating assembly 14 in a forward direction when feedback from the vehicle control modules 90 indicates that the front seating assembly 14 is unoccupied and a rear seat occupant has entered the rear seating assembly 18 (e.g. feet and/or legs sensed in the footwell 34, occupant sensor in the rear seating assembly 18 indicates the occupied status, etc.). The controller 46 may additionally verify that the front seating assembly 14 is in a position rearward of the forward-most position prior to activating the fore-aft actuator 118.

Referring to FIG. 5-7, methods for controlling a vehicle seating assembly 200A-C, such as the front seating assembly 14, are shown according to various embodiments. In FIG. 5, method 200A includes the step 202 of determining if rear easy entry/exit is selected by referencing the controller 46 to determine if the rear easy entry/exit option has been activated by a user. If step 202 determines that rear easy entry/exit is selected, then method 200A advances to step 208 for sensing an occupied status of the front seating assembly 14 to determine if an occupant is present in the front seating assembly 14, for example via the occupant sensor 22. If step 208 determines that the front seating assembly 14 is unoccupied, then method 200A advances to step 212 for detecting in the footwell 34 behind the front seating assembly 14 to determine if the object 30 is present. The detecting in step 212 may be accomplished, for example, by the proximity sensor 26. The proximity sensor 26 may detect the presence of the object 30 in the footwell 34 by sensing a change in a field emitted and/or sensed by the proximity sensor 26. The field emitted and/or sensed by the proximity sensor 26 may be an infrared field, a capacitive field, sonar, Light Detection and Ranging (LIDAR), or the like. If step 212 determines that the object 30 is present, then method 200A advances to step 216 for sensing a rear door open position, for example, with the rear door sensor 38. If step 216 determines that the rear door 42 has been opened, then method 200A advances to step 220 to actuate the actuator to move the front seating assembly 14 in a forward direction.

If step 202 determines that rear easy entry/exit is not selected, then method 200A advances to step 224 to determine if proximity sensing is activated, for example by the proximity sensor 26. If step 224 determines that proximity sensing is activated, then step 228 initiates deactivating proximity sensing and thereafter method 200A is terminated.

Referring now to FIG. 6, method 200B includes the step 202 of determining if rear easy entry/exit is selected. If step 202 determines that rear easy entry/exit is selected, then method 200B advances to step 208 for sensing an occupied status of the front seating assembly 14 to determine if an occupant is present in the front seating assembly 14, for example by the occupant sensor 22. If step 208 determines that the front seating assembly 14 is unoccupied, then method 200B advances to step 212 for detecting in the footwell 34 behind the front seating assembly 14 to determine if the object 30 is present. The detecting in step 212 may be accomplished, for example, by the proximity sensor 26. If step 212 determines that the object 30 is present, then method 200B advances to step 216 for sensing a rear door position, for example, with the rear door sensor 38. If step 216 determines that the rear door 42 has been opened, then method 200B advances to step 232 for detecting that the front seating assembly 14 is rearward of a forward-most position, for example with the fore-aft position sensor 98. If step 232 determines that the front seating assembly 14 is rearward of the forward-most position, then method 200B advances to step 220 to move the front seating assembly 14 in a forward direction.

If step 202 determines that rear easy entry/exit is not selected, then method 200B advances to step 224 to determine if proximity sensing is activated, for example by the proximity sensor 26. If step 224 determines that proximity sensing is activated, then step 228 initiates deactivating proximity sensing and method 200B is terminated.

Referring to FIG. 7, method 200C includes the step 202 of determining if rear easy entry/exit is selected. If step 202 determines that rear easy entry/exit is selected, then method 200C advances to step 204 to activate proximity sensing, for example with the proximity sensor 26. Once proximity sensing has been activated in step 204, method 200C advances to step 206 where it is determined whether the vehicle 10 is in motion, for example by referencing a speed sensor of the vehicle 10. If step 206 determines that the vehicle 10 is not in motion, then method 200C advances to step 208 for sensing an occupied status of the front seating assembly 14 to determine if an occupant is present in the front seating assembly 14, for example by the occupant sensor 22. If step 208 determines that the front seating assembly 14 is unoccupied, then method. 200C advances to step 210 where detecting movement of the front seating assembly 14 occurs. If step 210 determines that the front seating assembly 14 is not in motion, then method 200C advances to step 216 for sensing a rear door position, for example, with the rear door sensor 38. If step 216 determines that the rear door 42 has been opened, then method 200C advances to step 212 for detecting in the footwell 34 behind the front seating assembly 14 to determine if the object 30 is present. The detecting in step 212 may be accomplished, for example, by the proximity sensor 26. If step 212 determines that the object 30 is present in the footwell 34, then method 200C advances to step 232 for detecting that the front seating assembly 14 is rearward of a forward-most position, for example with the fore-aft position sensor 98. If step 232 determines that the front seating assembly 14 is rearward of the forward-most position, then method 200C advances to step 236 for sensing if a seat control button has been pressed by an occupant. If step 236 determines that no seat control button has been pressed, then method 200C advances to step 220 to move the front seating assembly 14 in a forward direction.

If step 202 determines that rear easy entry/exit is not selected, then method 200C advances to step 224 to determine if proximity sensing is activated, for example by the proximity sensor 26. If step 224 determines that proximity sensing is activated, then step 228 initiates deactivating proximity sensing and method 200C is terminated. If step 216 determines that the rear door 42 has not been opened, the method 200C advances to step 240 for sensing a front door position. If step 240 determines that the a front door is in an open position, then method 200C advances to step 244 for sensing if the front seating assembly 14 is in a last-known position. If step 244 determines that the front seating assembly 14 is not in the last-known position, then method 200C advances to step 248. Step 248 is for sensing if a seat control button has been pressed, similar to step 236. If step 248 determines that no seat control button has been pressed by an occupant, then method 200C advances to step 252 for moving the front seating assembly 14 to the last-known position.

Many of the vehicles 10 available today offer features that maximize the comfort of the occupants of the front seating assemblies 14. However, by maximizing the comfort of the occupants of the front seating assemblies 14, the comfort of the occupants of the rear seating assemblies 18 are sacrificed. Additionally, the comfort settings of the occupant of the front seating assembly 14, for example the driver, can impede access to items in the areas that are rearward of the front seating assembly 14. For example, a driver that has a child's car seat installed directly behind the front seating assembly 14 that the driver is occupying can impede access to the child's car seat and/or make ingress/egress of the child and/or child's car seat more difficult by moving the front seating assembly 14 rearward. The concepts and features disclosed herein alleviate this problem by providing a method of controlling a vehicle seating assembly to facilitate easier access to the object 30 that is rearward of the front seating assembly 14. Additionally, the comfort of the occupant of the rear seating assembly 18 is maximized in an automated fashion when the front seating assembly 14 is unoccupied. Further, ingress and egress of the occupant of the rear seating assembly 18 is made easier by the concepts and features disclosed herein.
